FCLOSEALL(3C) Standard C Library Functions FCLOSEALL(3C)

NAME

fcloseall - close all standard I/O streams

SYNOPSIS

#include <stdio.h>

int
fcloseall(void);

DESCRIPTION

The fcloseall() function closes all open standard I/O streams. The
equivalent of fflush(3C) is called on each stream before closing, thus
any buffered or pending input is discarded while any buffered or
pending output is written out to the underlying file. This includes
the standard streams, stdin, stdout, and stderr.

RETURN VALUES

Currently, the function fcloseall() always returns 0. Note, portable
applications should always check the return value.

INTERFACE STABILITY

Committed.

MT-LEVEL
Mt-Safe.
